Dev Mapper Vg_Vm-Lv_Root 少ない. Be careful before using the write command. The output of the next command will show the path to mount for the root lv.

Changes will remain in memory only, until you decide to write them. Edit the zvol to change the size. Note the partition name differs from config, this is correct and done by device mapper.
/Dev/Vg/Swapvol Does Not Exist Grub.cfg は、この例では Rd.lvm.lv=Vg/Swapvol という名前の Lv を読み込む構成で、Vm はこれを見つけ出す必要があります。 この行は、カーネルが Lv Swapvol を参照して読み込まれている方法を示しています
The server in question is using logical volume manager (lvm), which is a vastly superior way to manage storage space compared to just creating regular partitions with file systems on various disks. Be careful before using the write command. These are virtual block devices carved out of storage space allocated to one or more volume groups.
Next Create A New Volume Group, We Will Name This Vg As Test_Vg.
Note the partition name differs from config, this is correct and done by device mapper. Changes will remain in memory only, until you decide to write them. Then, i used resize2fs to grow the filesystem inside the logical volume.
The Easiest And Fastest Option Is To Create A Directory In /Home And Move All Data Of /Var To That Directory And Create Soft Link Of /Var To /Home/Var.the Steps Will Be As Follows.
Answering to save my future self some headache (since i've had to do this 3 times now): Once you get back, run parted with the device id, repair the gpt information and resize the partition, as per below. Proceed to mount this device on the directory /rescue.
The Output Of The Next Command Will Show The Path To Mount For The Root Lv.
If problem repeats when reboot the server go to #/boot/grub/grub.cfg at /vm/vmlinuz root=write your full lv path Use the swapon cmd to determine current system state: The devices in /dev/mapper are logical volumes.

#ls /dev/mapper you found root (like /dev/vgname/lvname) #reboot then select a kernel on a screen and select e to edit and paste a root value (like /dev/vgname/lvname) at /boot/vmlinuxxxxx root=uuid/dev/xxx. Edit the zvol to change the size. It gives you the hint of which lv and vg the root drive is using.
